How do hackers grab your personal data out of thin air? Supervisory Special Agent Donna Peterson of our Cyber Division said one of the most common types of attack is this: a bogus but legitimate-looking Wi-Fi network with a strong signal is strategically set up in a known hot spot...and the hacker waits for nearby laptops to connect to it. At that point, your computer—and all your sensitive information, including user ID, passwords, credit card numbers, etc.—basically belongs to the hacker. The intruder can mine your computer for valuable data, direct you to phony webpages that look like ones you frequent, and record your every keystroke.
“Another thing to remember,” said Agent Peterson, “is that the connection between your laptop and the attacker's laptop runs both ways: while he's taking info from you, you may be unknowingly downloading viruses, worms, and other malware from him.”
What can you do to protect yourself?
Agent’s Peterson’s best advice is, don’t connect to an unknown Wi-Fi network. But if you have to, there are some precautions you can take to decrease the threat:
• Make sure your laptop security is up to date, with current versions of your operating system, web browser, firewalls, and antivirus and anti-spyware software.
• Don't conduct financial transactions or use applications like e-mail and instant messaging.
Change the default setting on your laptop so you have to manually select the Wi-Fi network you’re connecting to.
• Turn off your laptop's Wi-Fi capabilities when you're not using them.
